APPARATUS FOR BOILING SAP OR CANE-JUICE.

SPECIFICATION forming part of Letters Patent No. 297,810, dated April 29, 1884.

Application filed February T, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, OBED II. J ONES, a citizen of the United States, and a resident of Kortright, in the county of Delaware and State of New York, have invented certain new and useful Improvements in Apparatus for Boiling Sap or Cane-Juice; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side view of my improved apparatus for boiling sap, cane-juice, or similar fluids; and Fig. 2 is a similar-view of the same, I

showing the track tilted and the boiling-pan removed from over thefire.

Similar letters of reference indicate corresponding parts in both the figures.

My invention has relation to apparatus for boiling or evaporating sap, cane-j nice, or similar fluids; and it consists in the improved construction and combination of parts of such an apparatus in which the pan is suspended from a truck traveling upon a track, which may be tilted by a weight when a given amount of water has been evaporated from the sap or juice, allowing the truck to roll away from over the fire, removing ,thepan with it, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the furnace or fire-place. B indicates upright posts, between which a track, 0, is pivoted, and the end of the said track which is over the fire-place isbent at an-obtuse' angle to the remaining portion, and rests, when in its horizontal position, with its outer end upon an abutment, D, when the remaining portion of the track is inclined upward, and that portion of the track may rest with its outer end upon an abutment, E, when it isin its horizontal position, the portion over the fire-place being then slightly inclined. A truck, F, travels upon the track, and is provided with downwardly-pending chains G, at the lower ends of which chains the boiling or evaporating pan H is suspended, and a chain or rope, I, is attached to one end of the truck, and

passes over a pulley, J, upon the longer end of the track, or thend which passes away from the fire-place, whereupon the depending end of the rope is provided with a weight, K, of sufficient weight to draw the truck and the pan after the latter have been sctin motion by 5 5 the tilting of the track. A rope or chain, L, is attached to the other end of the truck, passes over a pulley, M, at the abutment D, and serves to draw the truck and the pan back again over the fire.

N is an adjustable block, which may be secured at any place upon the track, servingto stop the truck. I

The outer end of the longer portion of the truclgortheportionleadingfromt-hefire-place, is provided with a receptacle, 0, into which may be deposited weights, and the track-being pivoted upon or between the uprights, it will be seen that if a certain weight is placed in the receptacleequal to overcome the weight of 7c the end of the track, the truck, the chains and pan, and the weight of the sap or juice when boiled down to a certain consistency-this weight will overcome the weight of the above named parts when the sap or juice has reached 7 5 the point when so much water has been evaporated to bring it to the desired consistency, at which consistency its weight in proportion to its quantity is known, and the weight overcoming the weight of that end of the track with all objects upon it, the track will be tilted and the pan be carried by the truck away off from the fire until the stopper upon the track will stop the truck. It follows that the track needs not necessarily to be composed of two portions 8 5 similar fluids, the combination of a pivoted 5 track having one end projecting over a furnace or fire-place, a truck traveling upon the track and having means for suspending the boilingpan, and weights at the end of the track, being sufficiently heavy to tilt the end of the track over the fire-place upward when the desired quantity of water has been evaporated, as and for the purpose shown and set forth.

2. The combination, in an apparatus for boiling sap, cane-juice, or similar fluids, of a fire-place, a track having the end placed over the fire-place bent at an obtuse angle to the other end of the track, pivoted upon an upright or uprights, and resting with its ends alternately upon abutments at each end, a truck traveling upon the track, and having the boiling-pan suspended from it by means of chains, a weighted rope passing over a pulley at the end of the track away from the fire-place, a
